Abstract:
Objective To evaluate the long-term clinical outcome of percutaneous coronary intervention ( PCI) with drug-eluting stents ( DES) for distal unprotected left main coronary artery (ULMCA) lesions. Methods Between Jan 2005 and Dec 2009, 111 patients with distal ULMCA disease who underwent drug-eluting stents implantation were enrolled in this retrospective study. The primary end points were major adverse cardiac and cerebrovascular event (MACCE) at follow-up, including death, non-fatal myocardial infarction, cerebrovascular event and target lesion revascularization ( TLR) . Results Patients were 65. 6 ± 10 years old. 21. 6% were diabetic. 31. 5% of the left main bifurcations were classed as Medina 1, 1, 1. Provisional T stent technique was performed for 79. 3% of the population. 30. 6% of cases underwent angiography follow-up. The median follow-up time was 2. 3 years, the MACCE-free survival was 87. 4% and the estimated freedom from TLR was 94. 6% . Diabetes mellitus was identified as the predictor of TLR. Conclusions PCI with DES for distal ULMCA disease was safe and effective when the strategy was made based on the case-by-case assessment.
